Hoid danced with Vatwha thousands of years before the True Desolation, but later, she was trained--presumably by Odium--to watch for Hoid.[1]

Hoid saw Vatwha in Kholinar after the Siege of Kholinar, hovering in the air, acting as sentry. Despite her training to spot Hoid, he still passed underneath her, and she gave him barely a glance. Hoid decided to not take it as an insult.[1]
